file upload not working

Thank you for your submission and thoughtful feedback.

Just a quick clarification on the file validator:

file_validate_extensions is the correct and Drupal-supported validator for #managed_file elements. The suggested FileExtension refers to a Symfony constraint class and is not applicable within Drupal’s Form API. Using it would result in validation issues.

That said, I appreciate you raising this and will review the file upload issue on Drupal 11 in more detail to ensure full compatibility. In the next release cycle, I’ll also consider your other suggestions around multi-app ID support and batching notifications for large-scale delivery.

Thanks again for contributing — looking forward to improving this together!

Thank you for reporting these issues and sharing your suggestions.

Latest Updates

1. JSON File Upload in Drupal 11

This issue has been resolved. The module was originally tested up to Drupal 10, and the file upload validator used was incompatible with Drupal 11. As suggested, the upload validator has been updated to:

'#upload_validators' => [
  'FileExtension' => ['json'],
],

2. Support for Multiple Application IDs

Currently, the form supports only a single application ID. I recognize the need to accommodate both iOS and Android app IDs and will consider this for a future release.

3. Sending Notifications to Multiple Devices

Firebase doesn’t allow sending to an array of tokens in one request via the current API, so notifications are queued and sent individually. However, I’m actively researching better ways to handle high-volume delivery more efficiently.

4. Multiple appId Values in Config Form

This is a valid feature request. I will explore adding support for multiple values in the appId field in future updates.

Thanks again for your detailed feedback — it's incredibly helpful in improving the module’s quality and usefulness.
